The economic activity had almost recovered to the pre-pandemic levels in most of the countries, before the latest wave struck. This wave seems to be very lethal and it is affecting younger people (maybe due to the nature of the mutation, or maybe due to the fact that the seniors have received at least one dose of the vaccine by now). One thing is sure. The only real solution we got now is to vaccinate as many people as possible. Almost 1 billion doses of the vaccine has been administered till now, and there have been very small number of reported side effects from vaccination. And we also have proof now, to confirm the fact that the number of cases were reduced in countries where most of the population got vaccinated. But the propaganda against vaccine during the early days had a large negative effect.
For instance, in Greece ages 30-39 started a few weeks ago, I'm now waiting for ages below 30 to start, in order to arrange an appointment for myself.
